Evidence
The June 9, 2026 release says Mackenzie introduced the Child Care Modernization Act and describes his earlier working-families tax package as having expanded the Child and Dependent Care Tax Credit and the employer-provided childcare credit, with those expansions included in the later Working Families Tax Cuts package.
Assessments
Mackenzie has taken same-term action consistent with part of the promise by introducing and advancing legislation to expand tax credits and reduce taxes for some working families. That supports partial credit for tax-cutting efforts. But the available evidence does not show that he broadly cut taxes or eliminated taxes through enacted federal policy, so the full promise is not delivered.
